Are there any commands and/or command+pipe+command comobinations that
will list the size of a directory from within the directory...??? I
remember reading something about an 'ls' | 'grep' | 'bc' that would sum
the sizes of every file in a directory and then output the result in
megabytes rather than blocks...???
Also, is there a way to list the number of files in a directory...??? I
used to pipe the output of 'ls' to 'wc' and it would display 3
numbers... I know what the first number is, but not the second or
third...???
Thanks...

Thanks for the reply, but thankfully I finally have TurboLinux up and
running... and so far so good. No crashes like windows and TBLinux comes
with lots of neato features... although I still need to find a good
wordprocessing program for it.
I'm not sure what the errors were really saying but after thinking about
my error and asking around a bit I did screw up with my partitioning and
just decided to make three partitions with fdisk. After this it worked.
Hmm... X is still kinda slowish, not really for a pentium 100 or should I
be expecting great performance? Perhaps a 32M swap was too small?
How's Redhat though? It seems to be one of the standard packages
around... but kinda pricy and too big to download.

I need more details.. Maybe your SCSI disk is not recognized by the kernel (if
you have one)
Wild guess.. but may help you if I know your system config

Subject: serial port source sample needed
Date: Fri, 30 Jun 2000 8:53:13 +0200
Hi,
I need to write some serial port communication routines for Linux, but so far
was not very successful with my tries (see below).
If someone could please point me to a simple sample that sends an "ATZ\r" out
to the port and displays the modems return string in just a few lines that'd
be great.
Here's what I tried so far - maybe someone sees the error (the init part is
similar to what I found in the Serial-Programming-HOWTO):
#include <sys/types.h>
#include <sys/stat.h>
#include <fcntl.h>
#include <termios.h>
#include <stdio.h>
main()
{
int c, res;
char buf[100];
struct termios newtio;
fd = open("/dev/ttyC7", O_RDWR | O_NOCTTY );
if (fd <0) { return 0; }
bzero(&newtio, sizeof(newtio)); /* clear struct for new port settings */
newtio.c_cflag = B2400 | CS8 | CLOCAL | CREAD;
newtio.c_iflag = IGNPAR;
newtio.c_oflag = 0;
newtio.c_lflag = ICANON;
newtio.c_cc[VINTR] = 0; /* Ctrl-c */
newtio.c_cc[VQUIT] = 0; /* Ctrl-\ */
newtio.c_cc[VINTR] = 0; /* Ctrl-c */
newtio.c_cc[VQUIT] = 0; /* Ctrl-\ */
newtio.c_cc[VERASE] = 0; /* del */
newtio.c_cc[VKILL] = 0; /* @ */
newtio.c_cc[VEOF] = 4; /* Ctrl-d */
newtio.c_cc[VTIME] = 0; /* inter-character timer unused */
newtio.c_cc[VMIN] = 1; /* blocking read until 1 character arrives */
newtio.c_cc[VSWTC] = 0; /* '\0' */
newtio.c_cc[VSTART] = 0; /* Ctrl-q */
newtio.c_cc[VSTOP] = 0; /* Ctrl-s */
newtio.c_cc[VSUSP] = 0; /* Ctrl-z */
newtio.c_cc[VEOL] = 0; /* '\0' */
newtio.c_cc[VREPRINT] = 0; /* Ctrl-r */
newtio.c_cc[VDISCARD] = 0; /* Ctrl-u */
newtio.c_cc[VWERASE] = 0; /* Ctrl-w */
newtio.c_cc[VLNEXT] = 0; /* Ctrl-v */
newtio.c_cc[VEOL2] = 0; /* '\0' */
tcflush(fd, TCIFLUSH);
tcsetattr(fd,TCSANOW,&newtio);
write(fd, "ATZ\r", 4);
res=read(fd,buf,20);
printf ("out: %d %s\n", res, buf);
}
I also thought that I could send commands out from the command line using
echo "AT\r" > /dev/ttyC7
which always hangs and see what's coming in using
tail -f /dev/ttyC7
which never shows anything. What's the point I'm missing here?
Any help's really appreciated.

Did you compile SCSI-Support as a module (or perhaps ext2)? You need
to have them in the kernel, otherwise the system would have to load
them in order to be able to load them...

I've tried this in /etc/security/limits.conf

A directory size in blocks is easy
du -s .
or bytes...
du -b -s .

Try man wc
What you get by default are the line, word & byte counts for the files
concerned...
What you want to do here is get ls to display one file per line & then
get wc to count lines. The ls option is -1 (that is a number one) and
the -l (a letter l) to wc ie
ls -1 | wc -l

I agree NT does_not_overwrite the MBR. I use a IBM Thinkpad 390X I can't use
LILO because the HD sector where supposedly have the MBR is used for
hybernation. To multiboot NT with Linux I'll have to use NT OS loader with
creating that BOOTSECT.LNX and add it at boot.ini. Since NT can't access the
MBR it should function at all as multiboot NT+Linux in my laptop.

Try booting a linux from a floppy and perform an e2fsck on the
partition.
You can find a good boot/root combi disc on the slackware site.
And just a thought, I don't see why anyone would want ext2 FS access
from windows, put all data you want in both OS's on a vfat partition and
mount that from linux. (this can ofcourse be your C: drive) (OK if you
put data in your $HOME, then you might want to able to access that, but
I never had any need for it)

Hi
This error message refers to vi's tempory file which it uses while editing,
and not to the Linux system swap file.
This file is usually created in /tmp. I note from your df figures that hda1
mounted on / is full.
Try to clear some disk space on the root filesystem.
Is this a particularly large file you are trying to edit?

While some versions of Red Hat are more prone to problems than others,

Use a rescue disk and at the boot prompt enter:
linux root=/dev/hdaX
where X is the correct device for root.
On my SCSI system I have to compile the scsi controller into the kernel
and not as a module.
